Scouting report: Miami will be without Dion Waiters (left ankle surgery), Rodney McGruder (left tibia surgery) and Okaro White (left foot surgery). Tyler Johnson (sprained left ankle) and Udonis Haslem (personal reasons) are listed as questionable. … Charlotte is 4-2 over its past six games and has posted the league’s sixth-best offensive rating during this stretch. … The Hornets have outscored opponents by 193 points with Kemba Walker playing. But the results have been terrible when Walker isn’t on the court, as opponents have outscored Charlotte by 187 points when the star point guard is not playing. … Four of the Heat’s past five losses have come against losing teams. … Miami is 15-5 this season when holding opponents to less than 100 points. … The Heat have outscored opponents by 30 points with Josh Richardson on the court over the past five games. … The Heat and Hornets have already faced off three times this season, with Miami winning all three games — the Heat beat the Hornets 105-100 in Miami on Dec. 1, the Heat beat the Hornets 104-98 in Charlotte on Dec. 15 and the Heat beat the Hornets 106-105 in Charlotte on Jan. 20.
